1. Feed

The stones blasted from the mountain are sent to the vibrating feeder through the dump truck. Vibrating feeder has strong adaptability, stable operation and high cost performance. It is a feeding equipment widely used in sand and gravel enterprises. The vibrating feeder can feed the crushing equipment continuously and evenly, effectively prolonging the service life of the equipment. Small volume, light weight, small power, compact structure, convenient installation, low operation cost and low investment cost.

2. Coarse and Fine Crushing

According to different crushing purposes, crushers are divided into coarse crushing and medium fine crushing: coarse crushers can process large stones to medium particle size at one time; The medium and fine crusher is mainly used to further crush and reshape the coarse crushed stone to meet the high standard requirements of construction projects for stone. The vibrating feeder evenly sends the stones to the jaw crusher, and the broken stones from the jaw are broken for the first crushing, that is, coarse crushing. The stones broken from the jaw are then transported to the cone crusher or impact crusher through the belt conveyor for secondary crushing, that is, fine crushing.

3. Sand Making and Screening

The finely crushed materials are sent to the sand making machine by belt conveyor for fine crushing, and the finely crushed materials are screened out by vibrating screen.

The general production line can be completed by the above three steps, but for those with strict requirements on the powder content of sand, a sand washer can be added after fine crushing and screening. Circular vibrating screen and linear vibrating screen are common in sand production line. Belt conveyor is the hub of sand production line. It has the advantages of low kinetic energy consumption, high production efficiency, large conveying capacity, flexible use, economy and practicality.

Manufactured Sand

Sand can be divided into natural sand and manufactured sand&#;

Natural sand: Rock particles with a particle size of less than 5mm, formed by natural conditions (mainly weathering of rocks), are called natural sand.

Manufactured sand&#;rock, mine tailings or industrial waste slag particles with particle size less than 4.7MM, which are made by mechanical crushing and screening after soil removal treatment, but soft and weathered particles are not included.

Advantages Of Manufactured Sand

1. The raw material of manufactured sand is fixed and produced after being broken by special crushing equipment. The mechanized production mode ensures the quality of manufactured sand is stable, adjustable and controllable, and can adjust the relevant parameters such as particle size distribution and fineness according to the needs of the project, which has better engineering applicability than river sand.

2. The surface of river sand is usually smooth after being scoured by water flow, while the manufactured sand has many sections and rough surface, so the machine-made sand particles can better combine with cementitious materials such as cement.

3. The raw materials of manufactured sand sand can come from some solid wastes. At the same time, in urban planning and construction, a large number of construction waste can be broken by mobile crusher to produce and process recycled aggregate, which not only solves the problem of environmental pollution, but also improves the utilization rate of natural resources.

4. During the period of shortage of river sand resources and rapid rise of raw material prices, the production cost of concrete enterprises can be reduced and the impact on the engineering field can be reduced.

9 Reasons And Solutions For Abnormal Vibration Of Sand Making Machine

Rotor is the core component of sand making machine. The principle of the sand making machine is to use the inertial kinetic energy of the rotor to rotate at a high speed to project the material in the circumferential direction through the channel of the rotor wheel, and impact the material accumulated on the impact anvil or the lining plate for impact crushing or shaping. The reshaped and rebounded materials are then crushed by the hammer plate integrated outside the high-speed rotor.

After the rotor vibrates for some reason, it is very likely to cause vibration of the entire equipment, and the vibrating rotor will greatly affect the use of the equipment, and even lead to failures. Here are 9 reasons and solutions for abnormal vibration of sand making machine.

• 1. Deflection Of Motor Shaft And Rotor Pulley
• 2. The Rotor Bearing Is Damaged
• 3. The Rotor Is Unbalanced
• 4. Material Blockage
• 5. The Foundation Is Not Firm Or The Anchor Bolts Are Loose
• 6. Feed Quantity Is Too Much Or The Size Of The Material Is Too Large
• 7. Bending Deformation Of Main Shaft
• 8. Wear Of Pulleys And Belts
• 9. Wear And Fall Off Of Wear-Resistant Parts

What are the common stone materials for making sand?

It is understood that as long as the water content of the ore is within a certain range, it can be used to produce manufactured sand by sand making machine. In the mining industry, there are nearly 200 kinds of stones can be used to produce manufactured sand, including solid wastes such as tailings, construction waste, coal gangue, etc. Here is an introduction to common manufactured sand materials and corresponding sand making equipment.

River pebble, granite, basalt, limestone, iron ore, etc.

These stones are all ideal materials in for building. They are hard in texture and can be used as raw materials in sand making production. For example, manufactured sand made of basalt can be mixed with concrete, which can reduce the weight of concrete, and also has the functions of sound insulation and heat insulation. It is a good aggregate for lightweight high-rise building concrete. The manufactured sand produced from river pebbles is often used for road paving and house construction. The stone powder produced in the production of machine-made sand from granite and limestone can also be reused.

These stones are mainly composed of feldspar and quartz, which belongs to sedimentary rock. They are good raw material for manufactured sand in terms of grain shape and strength, which can reach or even be better than natural sand. In addition, manufactured sand produced by sandstone also has the advantages of non-weathering, non-melting, sound absorption, and moisture-proof, and it is also a good building and decoration material.

When we use sandstone to crush into construction sand, it needs to go through the production process of crushing, sand making, screening, etc. The whole crushing plant needs to be reasonably matched to achieve low investment and high efficiency. According to the characteristics of sandstone, sandstone is suitable for the following equipment.

3. Tailings, construction waste, coal gangue, etc.

These stones belong to industrial solid waste. But with the advance of sand making process, these wastes are also "treasures", especially construction waste. In recent years, construction waste treatment is a very popular field in aggregates industry, and it has been sought after by a large number of investors. Construction wastes contains lot of crushed stones, concrete blocks, bricks and tiles, which can be crushed and made into new aggregates, and then used in highways and construction.

Using these industrial wastes to make manufactured sand can not only save costs and get high profits, but contribute to waste recycling.

How To Improve The Efficiency Of Pebble Sand Making Machine?

As important equipment for sand processing in manufactured sand production, the sand production efficiency is closely related to the overall benefit of operation. So, what method can effectively improve the sand production efficiency of sand making machine when crushing river pebble? Let's see it!

1. First of all, replace the shaft in time

Shaft is a very key point for the normal operation of the sand making machine, but it&#;s prone to wear out, so it&#;s necessary to replace the shaft every once in a while. It is cleaned during the replacement process and then lubricants should be added to make the shaft better serve the sand making machine.

2. Check the condition of the parts inside the machine regularly

If the vulnerable parts are not replaced in time, it will not only delay the production and affect the efficiency of sand making equipment, but also cause great damage to the equipment itself in serious cases. Therefore, users should develop the habit of checking the equipment regularly and replacing the worn parts in time.

3. Notice the tightness of the transmission belt

Excessive tightness will affect the power transfer of motor to the sand making machine, thus affecting the sand production efficiency. So it is necessary for users to pay attention to the tightness of the power transmission belt.

First, keep in mind the purpose of cow bedding is to provide a clean, dry and comfortable place for the lactating dairy cow. Of particular interest is minimizing teat end exposure to mastitis-causing bacteria at times when cows are particularly at risk for infection &#; like after milking. Second, the freestall and stall base should be a place where cows safely and confidently lay and stand, enter and exit.

Consider these five things when going to sand:

1. Stalls and stall conversions

Ideally, freestalls contain loose sand bedding that is 8&#; to 10&#; (20 to 25 cm) deep. But sand alone is not enough to compensate for poor stall design. This includes loops as well as critical dimensions: length, width, height, neck rail placement, brisket locator, etc.

If, for instance, a neck rail is improperly located toward the rear of the stall, the cow may perch in the beds and be unable to lay. If the neck rail is too far forward in the stall, the cow may lay too far forward and defecate in the stall beds, thereby negating one of the benefits of sand&#;that it is inorganic.

If stalls are too wide, cows may lay diagonally, causing manure and urine to be deposited in the stall beds. 

Mattress stalls can successfully be converted to sand. To do this, bedding retainers can be constructed from pipes, angle iron attached to the top of the curb or plate steel attached to the vertical face of the curb. Regardless of the bedding retainer type, allow for a sand depth of 4&#; (10 cm).

Stalls can also be converted by demolishing the existing curb and concrete base and replacing it with new curb. 

Removing a concrete stall base in preparation for sand bedding. 

Whether using bedding retainers or reconstructing stalls, follow these freestall design guides from Penn State and the University of Wisconsin.

2. Sand selection

Not all sand is created equally, nor is &#;free&#; sand always free. The number of different sand gradations are infinite, but they are usually referred to as either fine or coarse sand.

The selection of bedding sand is most often dictated by availability and/or the intended method of manure handling. Availability is simple: an abundance of the right sand at the right price. Beware of inexpensive or &#;free&#; sand. Often, this is either sand dug directly from the field, which may cause it to contain pebbles that can injure cows or organic matter that grows bacteria. Free or cheap sand can also be a byproduct of washing construction aggregates, in which case it may contain excessive amounts of silts and clays that will pack in stalls.

Concrete sand is a commonly accepted, readily available sand. It is a standard ingredient in concrete, available wherever concrete is made, and adheres to a standard size gradation. Concrete sand contains a balance of finer and coarser particles that allow it to stay loose in the stalls, but at the same time, concrete sand allows for high recovery in sand lanes and mechanical sand separation systems. 

Mason sand is another standard sand product and is finer than concrete sand. It is more desirable if the manure handling goal is to pump and haul sand-laden manure.

3. Filling stalls

Sand usage in freestalls is 50 pounds (23 kg) per cow per day. Sound like a lot? Not really, when you think about it. It&#;s a volume of sand 12&#; by 12&#; by 6&#; deep. Think about a cow shuffling along, entering/exiting a stall three times per day.

Filling stalls with a trailer-mounted Stall Filler.

When planning for sand bedding, remember to include a method for putting sand into stalls, which is typically done twice per week. Every four days, this equates to 200 pounds (90kg) per stall, or 10 tons per 100 cows.

To move sand in these quantities (bearing in mind the task of rebedding stalls must be accomplished in an hour or less), stalls must be filled using a high capacity Stall Filler. Stall Fillers (also known as bedding wagons or sand shooters) can be either trailer-mounted, truck-mounted or self-propelled. In any case, choose a machine designed to withstand the weight and the abrasive nature of sand. Design barn entrances, cross-alleys, concrete thicknesses, etc. to accommodate these large, heavy machines.     

4. Manure Handling

Often seen as the lone detriment to sand as dairy cow bedding, sand-laden manure handling is possible, but you need a plan. There are numerous proven and reliable methods for handling sand-laden manure. One of the best things to do is to avoid handling sand-laden manure using techniques and equipment intended for manure mixed with organic bedding. 

The challenges with handling sand-laden manure stem from two factors. First, sand is abrasive, so choose equipment designed to withstand the abrasiveness of sand. This means equipment that operates at low speeds and is constructed using wear-resistant materials like abrasion-resistant steel plate or rubber. Essentially, components in high-wear situations need to either be harder than sand grains or resilient enough to deflect without deforming. 

The second challenge is that sand settles, especially after dilution water is added. Sand-laden manure should never be put into tanks where settled sand cannot be safely and reliably removed. Sand-laden manure handling systems usually require additional agitation to fully suspend tank contents and/or ramps to allow for loader access.

Sand-manure separation systems are another option for dairy cow manure management where sand is used for bedding. Separation is accomplished by either sand lanes, which rely on gravity to settle sand and loaders to retrieve the settled sand, or mechanical sand separators, which rely on mining-duty technology to wash manure out of sand. Both systems successfully separate sand from manure. Sand recovery can be high enough to allow for anaerobic digestion (yes, sand bedding can be used along with anaerobic digestion).

Sand Separation System.

5. Sand recycling

Not only are sand separation systems capable of achieving high sand recovery, the separated sand can also be recycled with lactating dairy cows. Recycled bedding sand can potentially offset the cost of purchasing bedding sand by as much as 90-95%.

For sand recycling to occur, separated sand should be as clean and dry as possible. Elimination of organic matter also removes the water-holding capacity of recycled sand. Organic matter content should be as low as possible, with 2% being a maximum.

Recycled sand for dairy cow bedding.

With flush or flush flume systems, sand recovered from sand lanes tends to be wetter than sand from mechanical systems. Nevertheless, acceptable moisture levels can be achieved by stacking (with the drying achieved simply by time) or mechanically dewatered using mining-duty Sand Dewatering Screens.

Dewatering by stacking requires months to achieve an acceptable dryness, whereas mechanical dewatering allows for sand to be immediately recycled. Faster recycling of sand means less sand inventory. Less sand inventory means less cash being tied up in sand.

Sand can also be recycled where scraping or vacuum tanks are used to transport manure. Sand separation and recycling systems function differently than high-dilution sand lane systems since the water used for separating sand is most often acquired using the water obtained using solids separation. Regardless of the method of manure handling and transport (scrape or flush, vacuum tank or flush flume), clean, recycled sand is achievable. 

Keep these things in mind when you plan for your next sand barn. Using sand bedding isn&#;t necessarily difficult, rather it is really just different than using organic bedding. You&#;ll see the difference in your cows and your bottom line.
